【摘要】:目的建立L-02细胞中3-羟基-3-甲基戊二酰辅酶A(HMG-Co A)还原酶活性的检测方法。方法色谱柱:C18色谱柱,流动相:甲醇-水(20μmol·L-1磷酸二氢钾,p H 7.2)=6∶94,检测波长:340 nm,柱温:25℃,流速:1m L·min-1。考察该方法的专属性、标准曲线和定量下限、精密度与回收率、稳定性。结果还原型辅酶Ⅱ线性范围为2.5~1000μmol·L-1,定量下限为0.5μmol·L-1,日内、日间RSD分别在(5~6)%和(4~8)%内,相对回收率在(96.97~99.57)%内。结论建立的L-02细胞中HMG-Co A还原酶活性检测方法符合实验要求,且可用于测定氟伐他汀对L-02细胞HMG-Co A还原酶活性的抑制作用。
